Hello everyone, I have a problem with the automatic inventory part in zabbix,

so I created a test template to get some information from the PC, I wanted to test with a very simple template (which contains only 2 items), Here is the configuration of my first item :

And here is the configuration of my 2nd items:

I had tested whether the keys were functional beforehand, here is the test for my first item:

here is the test for my second item :

So I've checked that the keys work well so I'm normally able to retrieve these values from the zabbix web page 

what is not the case, I do not recover the values of my items I do not know why, the value of the item check_OS comes from another item present in another template which was formerly allotted to the host (obviously configured in the same way as my items present in the template of test, except that in the old item the value was not to supplement the field OS (Full details) of the tab inventory)
